Specification form-ing part of Letters Patent No. 221,495, dated November 1l,

October 10, 1879.

To all whom it 'may concern:

Be it known that l, LoRrNG W. BARNEs, of Attleborough, in the county of Bristol and State of Massachusetts, have invented new and useful Improvements in Buttons with Detachable Shanks; and I do hereby declare that the followingl is a full and exact description of the same.

My invention relates, mainly, to the mode of constructing thebutton; and it consists in a back plate fashioned with a cell for the locking bolts, and guide-loops for the pushers, all in one piece, and in a front plate, to which the male post is secured, with a circular corrugationor rib concentric therewith to form a recess to receive the head of the tubular shank, and to keep the lock-bolts in place, and leave a free space above the same for the actuatingspring and for the reception of any lint or other obstructing matter, which, if it could not escape, would clog the lock-bolts and render the device inoperative.

That others may fully understand my invention I will particularly describe it, having reference to the accompanylng drawings, Wherein- Figure 1 is a central vertical section of my button with parts all assembled. Fig. 2 is a similar section of the bezel and front. Fig. 3 is a front plan of the back plate. Fig. 4 is a plan ot' the front plate. Fig. 5 is a back plan of the back plate. Fig. Gis a central transverse section of the back plate.

A is the setting or face of the button, and B is the bezel or rim of the same, which holds and supports the setting and the workingparts.

C is the front plate, to the center of which the male stud or post D is securely attached. Behind the plate C is the back plate, E, the outer surface of which forms the visible back of the button, and between the plates G and E the working parts, consisting of the locks F, spring G, and pushers H H, are placed and conned. -These moving parts must be placed 'within certain guides, which will direct their movements and prevent their escape, and I therefore con struct the plateE with a depressed cell, e, across its center, as shown, particularly in Figs. 5 and 6, and I also, beyond the ends of said cell, form two raised loops, g g, beneath which the pushers are placed, and thereby the locks are kept down in place and position at 1879; application tiled one end. The plate E has a central orilice, r, through which the female post enters, and it may also be provided with aperipheral ange, h, whereby it may be more securely fastened Within the bezel B. This latter is n ot a necessity, however.

The plate C is provided with a circular rib or corrugation, d, concentric with the post D, and the space between said rib and said post forms a cell or recess, within which the head t' of the female post or shank J is housed when the separable parts of the button are brought together, and the elevation of said rib is such that it rests contiguous to the upper surfaces of the locks F F, and contines and keeps them in place at their inner ends.

The locking ends of the parts F are fashioned to embrace the female post J behind the head t', so that when said post is locked in place the parts F have an extended bearingsurface on said head t', and this tends to security and durability. I

The female post J is fitted to slide over the post D, and the head t' is beveled on its outer or front face, so as to enter between and force the locks F apart easily. At its outer end the post J is provided with the usual shoe, K,

The wire horseshoe-sprin g G, having its end bent over and hooked behind the edges of the lock-bolt heads, forces the locking ends of said bolts constantly toward the center and into engagement with the head t' whenever the lat ter is presented.

Each of the locks F, with its pusher H, is cut with die and punch from a plate of met al, and forms but a single piece. They are likewise duplicates otl each other.

It will be observed that each of the abovedescribed parts, aside from those which are exterior and ornamental, is the product of a machine, and, excepting the necessary soldering about the posts D and J, no manual labor is required to prepare these parts for their final assemblage in the button.

The plates C andE are each struck up complete in a die, and, if desired, may be secured in place with the working parts without solder by turning the back edge of the bezel inward over the edge of the iiange h.

Attention is also called to the fact that while the lockbolts F are securely confined in their cell, there is still an open space, S, behind them between the plates (T E, the space occupied in part by the spring G, and into this space any lint or other obstructing matter which inds its way into the eell E may pass and thns be prevented from obstructing the free Working of locks F.

Having described my invention, `what I claim as new is- 1. The back plate, l 1,constrncted in one piece with the depressed celle, and elevated loops gg, combined with thc looking-bolts F, substantially as set forth.

2. The lock-bolts and pnshers, constructed as described, combined with a plate, E, con strncted with a depressed cell, e, to receive said lock-bolts, and elevated loops` y to receive plates, C and E, and suitable guides for the locks F F, said plates beingseparated,as shown to leave a space, S, between them in free communication with the Space Occupied by said locks, for the purpose set forth.
